The present invention is a polymerizable compound (I), a polymerizable composition containing the polymerizable compound and a polymerization initiator, a polymer obtained by polymerizing the polymerizable compound or polymerizable composition, an optically anisotropic body in which the polymer is a constituent material, a carbonyl compound (4), a method for producing the polymerizable compound (I) characterized by reacting said compound and a hydrazine compound, and a method for using the carbonyl compound (4) as a raw material for producing the polymerizable compound (I). According to the present invention, provided is a polymerizable compound or the like that has a practical, low melting point, is highly soluble in general-purpose solvents, can be produced at low cost, and can yield an optical film that enables uniform polarization conversion in a broad wavelength band. Also provided is a carbonyl compound or the like that can be used as a raw material for producing the polymerizable compound or the like. (In formula (I), Y1 to Y8 represent -C(=O)-O- or the like, G1 and G2 represent a C1-20 divalent linear aliphatic group or the like, Z1 and Z2 represent a C2-10 alkenyl group that is unsubstituted or substituted with a halogen atom, Ax represents a C2-30 organic group having an aromatic ring, Ay represents a hydrogen atom or C1-20 alkyl group or the like, A1 represents a trivalent aromatic group or the like, A2 and A3 represent a C3-30 divalent alicyclic hydrocarbon group or the like, A4 and A5 represent a C6-30 divalent aromatic group or the like, and Q1 represents a hydrogen atom or the like.) |
